Research & Commentary: Gas Tax Hikes Are Not the Answer for Arkansas’ Roads

Published September 15, 2015

Early in 2015, Arkansas Gov. Asa Hutchinson (R) appointed the Working Group on Highway Funding (WGHF) to find ways to improve transportation funding. Arkansas’ current 21.5 cents-per-gallon gasoline tax and 22.5 cents-per-gallon diesel tax have not been increased since 2001. 

In August, a coalition of construction and contracting companies wrote a letter to WGHF calling for a 10-cent increase in the state’s motor fuel tax for the Arkansas Highway and Transportation Department. The proposed tax hike would raise an estimated $138 million, but not all of these funds would be used on state roads. The Highway Department would receive only $87.6 million of the new dollars; the remaining 36.5 percent would be divided between county roads, city roads, and administrative costs. 

Arkansas’ gas tax is already high compared to neighboring states, and increasing the tax would make the price of gas in Arkansas less competitive and fall most heavily on lower- and moderate-income Arkansans. Critics of the gasoline tax increase proposal say legislators should not use the current dip in gasoline prices as an excuse to hike taxes, and they note a tax hike would raise prices on goods and services throughout the economy, not just on gasoline. These increased costs are passed on to consumers. 

The main problem with transportation funding is irresponsible government spending, not with tax revenues. Far too many dollars are spent on projects unrelated to roads, such as bike paths and museums. If gas taxes are intended as a user fee, gas tax dollars should be spent only on roads and bridges. In The Wealth of Nations, Adam Smith argues when infrastructure is constructed and maintained utilizing user fees, new construction occurs only when demand justifies it. 

Only three years ago, the Arkansas sales tax was increased to help pay for highways. Americans for Prosperity-Arkansas noted in a press statement the Arkansas Highway Transportation Department has not proved it can spend new funds properly: “At the time, the Arkansas Highway Transportation Department (AHTD) claimed this would make our state’s highway system ‘among the best in the nation.’ Now, three years later, the highway department is back in front of the legislature pleading for more money. This time around, another tax increase isn’t the answer.” 

The Advance Arkansas Institute (AAI) argues there are better funding options that do not involve new taxes. One option AAI proposes is to allow the state Highway Department to access some of the state’s general revenue, which it says would glean the additional highway funding from existing revenue without raising taxes. Another option AAI highlights is state Rep. Joe Jett’s (D- Success) proposal to dedicate 25 percent of any “surplus funds” to fund highways.

As the rise in fuel efficiency continues, motor-fuel tax revenues will continue to decline. States and the national government will have to explore more modern and efficient ways to fund road construction and traffic infrastructure. These include privatizing roads and establishing toll systems. In several cities, transportation agencies are using congestion pricing—varying toll prices based on congestion—to manage demand and limit traffic problems. 

The following documents provide additional information about how motor-fuel taxes are applied and their effect on the economy.

Good Roads Group Calls for Special Session to Consider 10-Cent Gas Tax Hike
Steve Brawner of The City Wire examines efforts by the Arkansas Good Roads Foundation, a group advocating higher transportation spending, to push for a 10-cent-per-gallon increase in the state’s motor fuel taxes, which would raise an estimated $125.7 million for state highway needs.

Arkansas Shouldn’t Raise State Gas Taxes
Caleb Taylor of the Advance Arkansas Institute criticizes the proposed gas tax hike and makes recommendations for how legislators can improve transportation spending without a tax hike.

Paying at the Pump: Gasoline Taxes in America 
Jonathan Williams argues gas taxes can be an effective means of funding transportation improvements. In many cases, however, governments exploit the taxes for political reasons, spending them on projects unrelated to roads and other transportation improvements.  

Reconsider the Gas Tax: Paying for What You Get 
Jeffrey Brown of the University of California–Los Angeles notes the gasoline tax was created as a user fee to raise money for roads, but many politicians and the general public seem to have lost sight of this purpose and lump it together with other unpopular taxes. The challenge for policymakers, Brown argues, is to restore the connection in the public’s mind between the tax and the roads it should provide. 

Research & Commentary: Congestion Traffic Pricing 
Congestion pricing, an alternative to gasoline taxes, uses market principles to address traffic congestion. Under congestion pricing, operators of a road charge a variable price based on congestion, allowing the operator to manage demand and limit congestion. Heartland Senior Policy Analyst Matthew Glans examines several proposals for implementing pricing systems to alleviate traffic congestion.  

Fuel Taxes, Tolls Pay for Only One-Third of Road Spending 
Joseph Henchman of the Tax Foundation finds highway user taxes and fees made up just 32 percent of state and local spending on roads. Financing for the rest of the projects came out of general revenues, including federal aid. 

Raising Gas Taxes Won’t Fix Our Bridges
In the aftermath of the I-35 bridge collapse in Minneapolis, Minnesota, Adrian Moore of the Reason Foundation argues increasing fuel taxes should not be the only response to state transportation funding problems. Moore wrote, “First we must examine how we spend transportation dollars now. Then we maximize the value out of those dollars. Finally, the last step is to address the need for additional revenue.”
